Define LONG64 if __SIZEOF_LONG__ indicates 64-bit long

All modern compilers (GCC>=4.6, Clang>=3.0) define this macro, so we can
use it to detect 64-bit longs without adding to the architecture list.

This change allows me to successfully run a simple X11 window on a
64-bit FreeBSD RISC-V QEMU VM via SSH forwarding. Without this change
I get an error that DISPLAY cannot be opened.
